Description

Ian Ridpath reports to a studio reporter (not identified) on the theoretical discovery of 10th planet in Solar system by US astronomers. This was the result of the discovery of a moon going round Pluto which allowed calculation of mass of Pluto as smaller than our own moon and unable to cause gravitational effect observed on other planets so may be another body out beyond it causing these effects.
